Constants

const OPRF_CIPHERSUITE string = "OPRF-P521-HKDF-SHA512-SSWU-RO"

The ciphersuite used for the OPRF protocol

Types

type AssignmentData

type AssignmentData struct {
	VictimStateOfCurrentResidence    string
	CategorizationOfSexualMisconduct string
	IndustryOfPerpetrator            string
}

AssignmentData encapsulates the necessary information for DLOCs to assign matched users to LOCs. AssignmentData is onnly meant to be viewed by DLOCs.

type CallistoTuple

type CallistoTuple struct {
	// contains filtered or unexported fields
}

CallistoTuple represents the 6-tuple record sent by Callisto clients and received by Callisto servers

func NewCallistoTuple

func NewCallistoTuple(
	userId, pi, locCiphertext, dlocCiphertext []byte,
	encryptedEntryDataKeyUnderUserKey, encryptedEntryData, encryptedAssignmentData encryption.GCMCiphertext) (CallistoTuple, error)

NewCallistoTuple constructs a valid CallistoTuple. Returns a non-nil error if provided input is invalid.

func (CallistoTuple) DLOCCiphertext

func (c CallistoTuple) DLOCCiphertext() []byte

DLOCCiphertext returns the ciphertext to be decrypted by a DLOC

func (CallistoTuple) EncryptedAssignmentData

func (c CallistoTuple) EncryptedAssignmentData() encryption.GCMCiphertext

EncryptedAssignmentData returns the encrypted assignment data under k_a

func (CallistoTuple) EncryptedEntryData

func (c CallistoTuple) EncryptedEntryData() encryption.GCMCiphertext

EncryptedEntryData returns the encrypted entry data under k_e

func (CallistoTuple) EncryptedEntryDataKeyUnderUserKey

func (c CallistoTuple) EncryptedEntryDataKeyUnderUserKey() encryption.GCMCiphertext

EncryptedEntryDataKeyUnderUserKey returns the ciphertext protecting the random entry data key created for encrypting entry data. It can only be decrypted with the user's key.

func (CallistoTuple) LOCCiphertext

func (c CallistoTuple) LOCCiphertext() []byte

LOCCiphertext returns the ciphertext to be decrypted by a LOC

func (CallistoTuple) Pi

func (c CallistoTuple) Pi() []byte

Pi returns the pi value derived from P-Hat. Enables a Callisto server to find perpetrator matches between clients.

func (CallistoTuple) UserID

func (c CallistoTuple) UserID() []byte

UserID returns the userID of this tuple's submitter

type EntryData

type EntryData struct {
	PerpetratorName            string
	PerpetratorTwitterUserName string
	VictimName                 string
	VictimPhoneNumber          string
	VictimEmail                string
}

EntryData encapsulates information about the perpetrator and the victim. EntryData is only meant to be viewed by LOCs.

type LOCData

type LOCData struct {
	// contains filtered or unexported fields
}

LOCData encapsulates the 3-tuple plaintext that is encrypted for LOCs

func FromLOCDataMsgPack

func FromLOCDataMsgPack(msgPackEncodedData LOCDataMsgPack) (LOCData, error)

FromLOCDataMsgPack converts LOCData that is message-pack encoded into a LOCData struct

func NewLOCData

func NewLOCData(locType LOCType, shamirShare *shamir.ShamirShare, encryptedKey encryption.GCMCiphertext) (LOCData, error)

NewLOCData constructs a valid LOCData. Returns a non-nil error if provided input is invalid.

func (LOCData) EncryptedKey

func (d LOCData) EncryptedKey() encryption.GCMCiphertext

EncryptedKey returns the encrypted entry or assignment key. If LocType() is Director, then the encrypted assignment key is returned. If LocType() is Counselor, then the encrypted entry key is returned.

func (LOCData) GetShamirShare

func (d LOCData) GetShamirShare() *shamir.ShamirShare

GetShamirShare returns the (U, s) shamir share contained within LOCData

func (LOCData) LocType

func (d LOCData) LocType() LOCType

LocType returns either Director or Counselor. The result depends on the intended recipent of this data

func (LOCData) ToLOCDataMsgPack

func (d LOCData) ToLOCDataMsgPack() LOCDataMsgPack

ToLOCDataMsgPack converts LOCData into a struct that can be MessagePack encoded

type LOCDataMsgPack

type LOCDataMsgPack struct {
	LocType      LOCType
	U            []byte
	S            []byte
	EncryptedKey encryption.GCMCiphertext
}

LOCDataMsgPack encapsulates the same information as LOCData but is used for MessagePack encoding purposes

type LOCType

type LOCType int

An enum that represents the type of LOC

const (
	Unknown   LOCType = iota // Default case
	Director                 // Also known as DLOC
	Counselor                // Also known as LOC
)
